    Abstract

    An objective lens composed of a spherical Fresnel zone plate mirror and aspheric mirrors is designed. The Fresnel zone plate with spherical shape is analyzed, and the method to replace aspherical mirror with spherical Fresnel zone plate approximately is deduced. The objective lens is designed with a single spherical Fresnel zone plate mirror and three aspherical mirrors. Under the condition of magnification 100, Fresnel number 2.5 and field angle 120°, the modulation transfer function reaches above 40% at 0.6 line pairs/mm on the magnification side, and the distortion is less than 2.2%. This method can provide reference for application of Fresnel zone plate in visible light imaging, and possesses a bright future with the continuous development of fabrication technique of Fresnel devices.
